SPECIFICATION forming part of Letters Patent No. 721,547, dated February24;, 1903.

Application filed January 10, 1902. Serial No. 89,106. (No model.)

To all whom it may concern.-

Be it known that 1, CHARLES M. EARL,a citizen of the United States,residing at Detroit,in the county of Wayne, State of Michigan, haveinvented certain new and useful Improvements in Siphon-Fillers; and I dodeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanyingdrawings, and to the fig ures of reference marked thereon,which form a part of this specification.

This invention relates to a device for filling siphon-bottles andsimilar receptacles with carbonated water and other liquids underpressure, and it consists in the construction and arrangement ofpartshereinafter fully set forth, and pointed out particularly in theclaims. u

The object of the invention is to provide simple and efficient means formaintaining the siphon-bottle imposition, so that the liquid underpressure may be directed into the nozzle of the siphon and the valve ofthe siphon opened at the same time to allow the water to flow into thebottle. A further arrangement provides for a relief-opening which allowsthe liquid and gas occupying the channel between the controlling-valveand the siphon-nozzle to escape when the controlling-valve is closed,thereby preventing the escape of gas and water at the nozzle of thesiphon when the siphon is removed after the bottle has been filled.

The above object is attained by the structure illustrated in theaccompanying drawings, in which Figure 1 is an elevation showing myimproved apparatus and a siphon-bottle in position for filling. Fig. 2is a longitudinal section through the coupling and controllingvalve,showing the position of parts when the fluid under pressure is beingdirected into the siphon-bottle. Fig. 3 is a transverse section as online 3 3 of Fig. 2. Fig. Lisa sectional View similar to Fig. 2, butshowing the controlling-valve in position to cut off the flow designatesthe siphon-bottle,havin g the usual spring-controlled valve providedwith the projecting stem 2,adapted to be actuated through the lever 3 toopen the valve. A bracket lis attached to the under 'side of a bar orcounter (indicated by line 5 in Fig. 1) andis provided with a clamp 6,which embraces a coupling 7 and supports said coupling in position.Pivoted at 8 to the bracket 4 is a lever 9, adapted to bear upon theupper end of the valve-stein 2 when the siphon-bottle is in the positionshown in Fig. 1. Projecting from the rear of the coupling 7 is athreaded boss 10, adapted for attachment to a pipe leading from thepressure-reservoir (not shown) adapted to contain thecarbonated water orother liquid under pressure. Opening through said threadediboss 10 is anintake-port 11, which passesinwardly and downwardly and opens into asocket formed in the lower end of said coupling. Also communicating withthe socket in the lower end of said coupling is a passage-way 12, whichterminates in a nipple 13 at the couplings upper end. Surrounding saidnipple within an annular recess at the end of the coupling is acompressible washer 14.

Located within the socket at the lower end of the coupling is acompressible gasket 15, having openings therethrough which register withtheintake-port 11 and the passage-Way 12, respectively. Seated in saidsocket is a rotary plug-valve 16, havingin the face thereoftheinwardly-extending openings 17 and 18, connected at their inner ends bythe transverse channel 19, whereby a continuous passage is formedthrough the valve by way of said openings and channel. Screwed into theouter threaded opening in the recess at the bottom of the coupling is aplug 20, which surrounds the stem 21 of the valve 16 and 2,communication is established between the intake-port and the passage-way12 by way of the valve 16.

When desiringto fill the siphon-bottle, the nozzle 23 of the siphon isplaced over the nipple 13 and against the compressible washe 14,surronndingsaid nipple, as shown in Figs. 1 and 2. By a downwardpressure upon the lever 9 the valve-stein 2 is depressed to unseatthesighon-valve and at the same time force the siphon-nozzle onto thewasher surrounding the nipple 13, thereby making a tight couplingbetween said nozzle and the discharge end of the passage-way 12. Thevalve 16 is then opened or turned to the position shown in Fig. 2, whenthe fluid under pressure will flow through said valve and through thenozzle of the siphon in the bottle. When the bottle has been filled, theflow of liquid is cut off by closing the valve or ro tating it so as tocarry the apertures 17 and 18 therein out of alinement with theintakeport 11 and the passage-way 12, which position is shown in Fig. 4.To provide for an escape of the fluid contained in the passageway 12when the valve 16 is closed, said valve is provided with adischarge-opening 24, which extends inwardly from the face of the valveand thence diametrically thereof between the openings 17 and 18, itsdischarge end passing through the side of the valve and communicatingwith the relief-port 25, passing through the wall of the coupling,whereby all gas and water under pressure contained in the passage-way 12finds immediate escape, enabling the siphon-bottle to be removed fromthe coupling without spurting or sniffing as the nozzle is withdrawnfrom the nipple 13. It will be observed that the arrangement is such asto cause the discharge-opening in the valve to register with thepassage-way 12 only when the valve is closed to cutoff the flow ofliquid through the port 11 and that when the valve is open to allow theliquid to flow into the siphonbot-tle the discharge-port in said valveis out of alinement with said passage-way 12, as shown in Fig. 3.

For the purpose of supporting the bottle firmly in position whenplacedon the coupling for refilling an inclined plate 26 is screwed ontothe lower end of the coupling and secured by a jam nut 27, thedownwardly-extending end of said plate being concave, as at 28, toreceive the round of the bottle and maintain it in position while beingfilled.

It will be observed that in this apparatus the controlling-valve doesnot depend upon the action of a spring to close it, therefore obviatingthe failure of the valve to close through a weakening of the spring orthe accumulation of some substance upon the valveseat. It will also beobserved that simultaneously with the closing of the controllingvalve arelief is provided for the fluid under pressure remaining in thepassage-way 12, so that an escape of fluid at the nozzle of the siphonis obviated as the bottle is removed from the coupling.

Having thus fully set forth my invention, what I claim as new, anddesire to secure by Letters Patent, is-

1. In a siphon-filler, the combination of a stationary coupling havingan intake-port adapted to be connected with a source of fluid underpressure and having a passage-way extending from end to end of saidcoupling, a member at the terminal of said passage-way adapted toreceive a siphon-nozzle, a controlling-valve in said coupling adapted byits movement to connect the intake-port with the nozzle of the siphonthrough said passageway, a relief-port through the wall of the coupling,and a discharge-opening in said valve adapted to connect the passage-wayleading to the nozzle of the siphon with said relief port when thecontrolling valve is closed.

2. In a siphon-filler, the combination of a coupling, an intake-port insaid coupling connected with a source of fluid under pressure, apassage-way through said coupling, a nipple at the terminal of saidpassageway adapted to receive a siphon-nozzle, a valve in said couplingprovided with an opening adapted to connect said intake-port with saidpassageway, a discharge-opening in said valve, a relief-port in the wallof the coupling, said discharge-opening being adapted to connect saidpassage-way and nozzle with said relief-port in the wall of the couplingwhen the valve is closed.

3. In a siphon-filler, the combination of a coupling, an intake-porttherein connected with a source of fluid under pressure, a passage-waythrough said coupling, an external nipple at the discharge end of saidpassageway adapted to receive a siphon-nozzle, a compressible washeraround said nipple, a valve adapted to establish communication betweenthe intake-port and said passage-way, a reliefport through the wall ofthe coupling, and means operated upon the closing of the valve forconnecting said passage-way with the atmosphere through saidrelief-port.

In testimony whereof I sign this specification in the presence of twowitnesses.

CHARLES M. EARL.
